Plastic Sheet
- Most people seem to be using a 12x12" mylar sheet; they are available at most craft stores and Amazon.com -- its a thin plastic, very clear and comes in thicknesses measured in mm -- for example 4m

- A more industrial alternative is polycarbonate; most construction work face shields are made of this
- Sheet can be cut to size and are a few dollar per square foot

Bands:
- any elastic band will do; the fastest option is a tourniquet; you need to fashion it under tension into grooves for it to stay in place
- ideally use something that does not absorb moisture and is chemical resistant; so you can toss it into cleaning agent (most designs use a band that can absorb moisture -- best agents would be rubbers; silicone ideally and cheapest would be large rubber bands

- I'll share a mold for casting your own bands with silicone rubber; which would be reusable and easily cleaned.
Rigid Plastic:
- Cheapest options for the 3D printer are PLA and ABS -- abs is super inert (lego plastic!); either should do fine in terms of chemical resistance; but then again depends on the solution we end up using
- bleach doesn't seem to degrade PLA
